Professor who campaigned to ban trans fats dies at 102

Fri, 06/02/2017 - 13:21
Fred Kummerow sounded equal parts relieved and content on that Tuesday afternoon in June 2015. The Food and Drug Administration had decided to ban artificial trans fats from the U.S. food supply, finally eliminating a key culprit in the rising rates of heart disease in the nation. Kummerow, then a 100-year-old University of Illinois professor, had […]Related:‘Drug tourists’ keep overdosing at this library.

Twist of fate: Anna reconnects with the oncologist who saved her life

Fri, 06/02/2017 - 11:00
Credit: Mark Dela Cruz Anna Protsiou was five in 2002 when she was diagnosed with neuroblastoma. She remembers pain and the fruit-scented anesthesia masks that led her to stop eating cherries. She remembers hospital arts and crafts projects. What she barely remember is the pediatric oncologist who saved her life. She was a young girl then who didn’t speak English, moving with her family from their native Greece to be treated for a year at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center. Now, after moving with her family to Canada in 2014, she’s a 20-year-old dance student at the Eg. School of Contemporary Dancers/ University of Winnipeg and a contortionist with a rubber-band body. She’s ready to claim her history as her own, ready to move beyond photographs of the d...

Could You, Would You Save A Life? This CPR-AED Awareness Week, Vow To Know How

Tue, 05/30/2017 - 12:27
As she prepared for the PurpleStride 5K in Kansas City a few weeks ago, Brooke Worrel took her time attaching the racing number to her shirt. This usually mindless task was a lot tougher with all the tears filling her eyes. One year before, she ran this race with her dad. She finished. He didn’t. Shortly after crossing the finish line, 16-year-old Brooke went back on the course to join Rick at the end of his run. When she reached him, Rick was on the ground, blood pouring from the left side of his face and his right knee. Men on both sides of him were performing CPR. *** Rick Worrel’s grandfather died at age 55. So did his dad. Rick was 55 when he and Brooke ran that 5K on May 14, 2016. But Rick’s heart story dates to the day before Thanksgiving in 2014. To a routine trip to the gym...

Artificial intelligence accurately predicts stroke risk

Thu, 05/25/2017 - 17:06
[Image from unsplash.com]Machine-learning algorithms, a form of artificial intelligence, accurately predicted people’s risk of heart disease and stroke, according to new research from the University of Nottingham. Researchers and computer scientists compared the risk guidelines for heart disease and stroke from the American College of Cardiology with 4 machine-learning algorithms to analyze the risk of a patient having each. The results showed that the artificially intelligent algorithms were significantly more accurate at predicting cardiovascular disease than the regular medical models.

Apple Watch detects atrial fibrillation using built-in technology

Tue, 05/23/2017 - 19:09
[Image from unsplash.com]The Apple Watch can automatically detect atrial fibrillation (AF) using its built-in heart rate sensor and artificial intelligence, according to a new study. The research used a deep neural network that was based on photoplethysmographic (PPG) sensors that are frequently found in smart watches. When paired with an artificial intelligence-based algorithm, Apple Watch’s heart rate sensor can detect AF. There were 6,158 participants in the University of California San Francisco Health eHeart Study who all used Cardiogram for the Apple Watch. The data gathered from the study was used to train a deep neural network to distinguish AF from normal heart rhythm automatically. Get the full story on our sister site, Medical Design & Outsourcing.

Harvard researchers reveal ‘ JetValves ’ , nanofiber heart valves with potential to regenerate, grow

Thu, 05/18/2017 - 17:46
In this study, we used a combination of synthetic polymers and ECM proteins to fabricate biocompatible JetValves that are hemodynamically competent upon implantation and support cell migration and re-population in vitro. Importantly, we can make human-sized JetValves in minutes – much faster than possible for other regenerative prostheses,” JetValve team lead Kevin Parker of Harvard’s Wyss Institute said in a prepared release. Today, both groups said they formed a cross-institutional team looking to generate a functional heart valve replacement with regenerative, reparative and growth potentials. The teams will also work towards creating a GMP-grade version of their manufacturing process to enable larger-scale production. The heart valves can be manufactured in all desired s...

FDA panel recommends approval for TransMedics lung transplant device

Thu, 05/18/2017 - 15:54
An FDA advisory panel yesterday recommended that the federal safety watchdog approve a device made by TransMedics to keep donated lungs perfused during transport to transplantation procedures. The FDA’s Gastroenterology & Urology Devices panel voted 11-2 that the OCS Lung system is safe; 8-5 that it’s effective; and 9-4 that its benefits outweigh the risks, an FDA spokeswoman told MassDevice.com via email. TransMedics did not respond to a request for comment. A previously scheduled advisory panel hearing for another TransMedics device, the OCS Heart system, was cancelled by the FDA in November 2015. The agency told MassDevice.com at the time that “FDA has determined that an advisory committee is no longer needed to discuss the premarket approval application&#822...

Medtronic looks to settle TAVR patent spat with doc inventor

Tue, 05/16/2017 - 15:17
Medtronic (NYSE:MDT) is looking to settle a patent infringement dispute over transcatheter aortic valve replacements with a doctor who sued the company and cross-town rival St. Jude Medical (NYSE:STJ), which last week lost its bid to have the case dismissed. Dr. Robert Snyder, founder of Snyders Heart Valve, filed suits last year in the U.S. District Court for Eastern Texas claiming that both companies used technologies covered by his patents for an artificial heart valve and delivery system called the Funnel valve, according to court documents. The lawsuits, which were later consolidated, allege that St. Jude’s Portico valve and Medtronic CoreValve and CoreValve Evolut implants infringe a pair of his patents. St. Jude moved to have the case dismissed for lack of venue, arguing tha...

What Causes Anemia?

Sun, 05/14/2017 - 23:29
Discussion One of the most common problems in pediatrics is anemia. It is defined as “a lower than normal value for the related measurements of hemoglobin, hematocrit, and number of red blood cells”, usually 2 standard deviations below the normal for age. Normal hematological values change with age. For a discussion of which values are used click here. The most common type of anemia in childhood is iron deficiency which is commonly caused by inadequate stores (e.g. premature infant), inadequate intake (e.g. poor nutrition) or blood loss (e.g. menses). Anemia screening is recommended at age 9-12 months, and for adolescent males and females during routine health examinations. As iron deficiency is the most common cause, often a trial of therapeutic iron (2-6 mg/kg/day of element...

Study suggests link between imbalanced gut microbiome and systemic sclerosis

Fri, 05/12/2017 - 22:07
This study is the first to examine gastrointestinal bacterial composition in two independent groups of people with systemic sclerosis. Systemic sclerosis, also known as scleroderma, is an autoimmune disease affecting the body ’s connective tissue. It is characterized by a hardening and scarring of skin and can progress to inflammation and scarring in the organs such as kidneys, heart, lungs and gastrointestinal tract. Previous UCLA-led research  detailed a link between the disease and the imbalance in the gut microbiome and suggested that this imbalance contributed to scleroderma’s symptoms.METHODThe researchers studied 17 adults with systemic sclerosis from UCLA, 17 from Oslo University Hospital, and 17 healthy adults as the control group. All participants provided stool specimens, ...
